Researchers determined that 60 Kleenex tissues is the average number of tissues used during a cold. Suppose a random sample of 100 Kleenex users yielded the following data on the number of tissues used during a cold: x = 52 and s= 22. Suppose the alternative we wanted to test was H₁ < 60. The correct rejection region for a = 0.05 is Select one: O O a. reject Hif t > 1.9842 or Z< -1.9842 b. reject H if t < -1.6604 c. reject Hif t> -1.9842 d. reject H if t > 1.6604 e. reject H if t< -1.9842

is
Select one:
a. reject H
b. reject H if t < -1.6604
c. reject Hif t> -1.9842
d. reject H if t > 1.6604
0
if t > 1.9842 or Z< -1.9842
e. reject H if t < -1.9842
